Product Information

Product Details
Part No. 4212
Warranty Details (60 DAY REPLACEMENT IF DEFECTIVE)
NGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in distributorless ignition systems.

Product Features:
  • ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction fine wire iridium alloy center electrode provides consistent performance
  • IRIDIUM ALLOY CENTER ELECTRODE: Iridium's density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
  • PLATINUM TIP GROUND ELECTRODE: Unless OE specified, platinum protection at the ground electrode provides excellent ignitability and service life
  • SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
  • TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
  • RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
  • Superior Durability: The iridium-tipped center electrode is six times harder than platinum, ensuring long-lasting performance and reliability.
  • Optimized for OE Applications: Engineered specifically for Original Equipment (OE) applications, meeting the highest standards for quality and durability.
  • Even Wear: Features a platinum pad on the ground electrode, designed to provide even wear in distributorless ignition systems.
  • Fine Wire Tip Design: The fine wire tip design of the ILFR6G-E model ensures efficient and effective spark delivery for optimal engine performance.
